Sbatch options.

So you get a total of 24 CPUs across multiple nodes. For your second example, the sbatch --ntasks 1 --cpus-per-task 24 [...] will allocate a job with 1 task and 24 CPUs for that task. Thus you will get a total of 24 CPUs on a single node. In other words, a task cannot be split across multiple nodes. Therefore, using --cpus-per-task will ensure ...sbatch options¶ A complete list of sbatch options can be found here, or by running man sbatch. Options can be provided on the command line or in the batch file as an #SBATCH directive. The option name and value can be separated using an '=' sign e.g. #SBATCH --account=nesi99999 or a space e.g. #SBATCH --account nesi99999.
